Product DescriptionQ460NE steel plate is a kind of high-strength low alloy structural steelQ460NE steel is a type of high-strength low-alloy structural steel. Due to its excellent mechanical properties and welding performance, it has been widely used in fields such as bridges, buildings, and ships.SpecificationCore performance and technical indicatorsMechanical Properties1. High strength bearing: When the nominal thickness is ≤ 16mm, the yield strength is ≥ 460MPa, and the tensile strength reaches 540-720MPa; even when the thickness increases to 150-200mm, the yield strength remains ≥ 370MPa, and the tensile strength remains at 530-710MPa.This high strength characteristic enables significant reduction of steel usage in large structures, achieving lightweight design. 2.Excellent low-temperature toughness: For grade E quality, it requires a longitudinal impact absorption energy of ≥ 31J at -40℃ and a transverse energy of ≥ 20J, effectively avoiding the risk of brittle fracture at low temperatures, and suitable for bridges and offshore platforms in extremely cold regions. 3.Plasticity and fatigue resistance:The elongation rate is ≥ 17% (some data show ≥ 20%), and it has good fatigue resistance, capable of operating stably for a long time under alternating loads. 2. Chemical Composition Design .Basic elements: Carbon content ≤ 0.20%, silicon ≤ 0.60%, manganese 1.00-1.70%, through reasonable proportioning to balance strength and weldability. 4.Micro-alloy strengthening: Elements such as niobium (Nb 0.01-0.05%), vanadium (V 0.01-0.20%), and titanium (Ti 0.006-0.05%) enhance strength and toughness through precipitation strengthening and grain refinement.5. Impurity control: Phosphorus ≤ 0.025%, sulfur ≤ 0.020%, reducing the negative impact of harmful elements on performance.Production Process and Delivery ConditionsStrict Rolling and Heat TreatmentThe normalizing or normalized rolling process is adopted. By precisely controlling the rolling temperature (for example, the starting rolling temperature of rough rolling ≥ 1050℃, and the finishing rolling temperature is 820±10℃) and soaking time (30 - 60min), the grain refinement and property uniformity are ensured.Heat treatment methods also include annealing, normalizing plus tempering, etc. The lower limit of the tempering temperature is 675℃ to optimize the comprehensive mechanical properties.Delivery ConditionsIt is usually delivered in the normalizing (N) or normalized rolling state. Some need to be inspected for flaws (such as GBⅠ level) to meet the needs of high - end engineering projects.right elevationleft elevationfront elevationAfter Sales ServiceStandard Warranty: 12 months or 2,000 operating hours (whichever comes first).Extended Warranty: Optional coverage up to 36 months.Global Support: 24/7 technical assistance and spare parts supply.Training: On-site or remote operation/maintenance training.Company ProfileWelcome to Evergrowing Resources Co.
